In my opinion, easily the weakest Ys game, and especially even more so in this engine as I thought Origins was more fun. So much grinding, kind of tedious to play. This never felt like just a fun game, there was just always something lacking. I think a lot of other people enjoy the difficulty of it, but it never felt like fun difficulty, it felt like unnecessary tedium. The one saving grace was that this game actually had more then two difficulty options so I could at least get through it.

Worst one of the series, most dungeons have convoluted leveldesign while being not that various in terms of secrets compared to Ys VI (2003, this game is 2005 btw), retarded placement of enemies and checkpoints, also dumb platformer sections that even some bossfights have.
Hard difficulty will rape your ass, there's differences in bossfights too because of it.
Grindy shit overall, can't say anything good about it.
Abandoned right at the last bossfight
